How We Evaluated the Subaru Forester Model Years
Our analysis examines official safety recalls, manufacturer service campaigns, and long-term ownership patterns. We weigh the severity and recurrence of mechanical failures against repair complexity.
Consumer complaints indicate owner frustration but do not automatically confirm a widespread mechanical defect. Similarly, a safety recall does not inherently make a specific model year unreliable if repaired.
Recent model years naturally possess less ownership history. Therefore, our top recommendations reflect comparative strength and proven maturity rather than absolute perfection.
Best Subaru Forester Years
2015–2018 (Best Choice)
These years represent the mature phase of the fourth generation. Subaru addressed the earlier FB25 oil consumption issues and refined the Lineartronic CVT programming.
Buyers gain a highly capable all-wheel-drive crossover with excellent safety ratings. The 2.5-liter engine is now exceptionally durable with routine maintenance.

Best Family Alternative: Subaru Outback
Buyers needing more cargo space should consider the Subaru Outback. It shares related architecture and powertrains with the Forester but offers a longer wheelbase and lifted wagon profile.
Years to Approach Carefully
2012–2014 (Approach Carefully)
The introduction of the FB25 engine brought severe oil consumption issues due to defective piston rings. This prompted a Subaru warranty extension for affected short blocks.
Buyers must verify if the engine short block was replaced under warranty. The early CVT programming in these years may also exhibit occasional stalling or hesitation.
2009–2011 (Good With Inspection)
The third generation refined the cabin but retained the EJ25 engine, which remains prone to external head gasket leaks. The 2.5XT turbo models face additional ringland failure risks.
Verify service records for head gasket replacements and turbo health. A documented repair history makes these years reasonable, but neglect leads to expensive engine teardowns.
2003–2008 (Good With Inspection)
The second generation offers a practical footprint and reliable all-wheel drive. However, the EJ25 head gasket flaw is prevalent, and aging electrical components require attention.
Inspect the engine block for coolant weeping. The 2.5XT models from this era demand strict maintenance to prevent turbocharger and intercooler failures.
Worst Subaru Forester Years
1998–2002 (Avoid)
The first generation suffers from the earliest iterations of the EJ25 engine, which are notorious for catastrophic head gasket failures. The single-layer gasket design fails prematurely.
Combined with severe age, obsolete safety equipment, and aging wiring harnesses, these models are a poor investment. Buyers should look at newer generations for reliable transportation.
Subaru Forester Reliability by Generation
First Generation (1998–2002)
These early models are simple but heavily affected by head gasket leaks. They are best left to enthusiasts willing to perform extensive restorations and engine resealing.
Second Generation (2003–2008)
This era improved the interior and introduced the turbocharged XT model. The naturally aspirated models still require head gasket vigilance, while the XT demands meticulous oil change intervals.
Third Generation (2009–2013)
The third generation offered more space but retained the EJ25 engine through 2011. The 2012–2013 models introduced the new FB25 engine, which suffered from early oil consumption defects.
Fourth Generation (2014–2018)
Widely considered the most practical used generation. The 2015–2018 models feature sorted FB25 powertrains and improved CVT tuning, making them excellent daily drivers and light off-roaders.

The current generation introduces a complete redesign with updated styling and hybrid options. It remains too new to evaluate for decade-long durability, but early reports are favorable.
Common Subaru Forester Problems
Engine Head Gasket Failures
Primarily affecting 1998–2011 models with the EJ25 engine. The factory gasket material degrades, allowing coolant and oil to leak externally. This requires an expensive engine removal to repair.
Excessive Oil Consumption
Found mainly in 2012–2014 models with the early FB25 engine. Defective piston rings cause rapid oil burning, potentially leading to engine damage if fluid levels drop unnoticed.
CVT Transmission Stalling
Owners of early 2014–2015 models frequently report stalling when coming to a stop. Subaru issued technical service bulletins and software updates to resolve the valve body programming issues.
Turbocharger Failures
Affecting 2.5XT models across multiple generations, particularly when maintenance is neglected. Starved oil or contaminated fluid leads to turbo failure, which can send metal debris into the engine block.
What to Check Before Buying a Used Subaru Forester
- Verify Recall Status: Enter the VIN on the NHTSA website to confirm all airbag and fuel pump recalls are closed.
- Inspect Head Gaskets: On 1998–2011 models, check the lower engine block for signs of coolant or oil weeping.
- Monitor Oil Levels: On 2012–2014 models, check maintenance records for short block replacements or frequent oil top-offs.
- Test the CVT: Drive the vehicle in stop-and-go traffic to check for stalling, hesitation, or unnecessary shuddering.
- Evaluate Turbo Health: On XT models, listen for unusual wastegate rattles and inspect the intercooler for cracking or oil residue.
